On IBs TWS: Receive Delayed Market Data

This may be interesting for some users of TWS (version 900 - latest release)

"Receive Delayed Market Data

Customers now have the option to receive delayed market data for exchanges and instruments for which they do not current hold market data subscriptions. The Market Data Request Error window, which displays when the user attempts to add a ticker without having subscribed to market data, now includes two checkboxes at the bottom of the window. Check Receive available delayed market data to use delayed data (if available) for the specific instrument. Additionally check Automatically receive delayed market data when available to use available delayed data automatically whenever you add a ticker to your trading page on an exchange for which you do not hold a market data subscription. The trading window highlights tickers that use delayed data in yellow for easy identification.

The delayed data shows and updates on the trading page in 900.3, but when you open a chart no data is shown, and 'No market data permissions for (symbol)' appears in the menu bar. Data does show in the chart's Quote Panel. How do you get the chart to populate for GBL Z09 for example.
